I gave this game a good review...at first until...
(I've played it on all the difficulties and its too easy in my opinion)
First error: you can tell your partner to open a door and throw a frag or flash grenade… 3 out of 5 times he turns and throws it at me blinding me or almost killing me.
Second error: once in a while I fall and die randomly and there's no one around (I know cause I beat the game and these no one in that region.)
Third error: A headshot always kills your teammate so you automatically lose and your lock on aimer sucks unless very close range (because your bullets go through the person but doesn't not hurt him).
Fourth error: You tell your partner to hold fire and stay back but as soon as you get shot he rushes in to help (even when you don't need it) and gets badly injured (or killed).
Fifth and final error: This hardly happens but your bullets hit an invisible wall in front of you.
The game play is fun and the missions are fun to (repetitive) so I give this game a 6.5
